Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one optical fiber cable is used for sensing, then the device complexity is reduced, but the spatial sensing capability is lost
Solution Approach 1:
The patent transitions from one-dimensional linear sensing along a single optical fiber cable to three-dimensional spatial sensing by deploying multiple optical fiber cables in different spatial directions (vertical, horizontal, inclined). This dimensional expansion enables the system to detect object locations in three-dimensional space by integrating sensing data from multiple cables positioned at different orientations and locations.
2Ease of operation
If one optical fiber cable is used for sensing, then the system is simpler to operate, but the measurement precision of object location is insufficient
Solution Approach 1:
The patent divides the sensing task into multiple segments by using several optical fiber cables instead of one. Each cable independently provides sensing data from its specific location and orientation, and the object detection unit integrates these segmented data sources to achieve precise three-dimensional location measurement that cannot be obtained from a single cable.
